PAPER FASTENER.

Application filed November 12, 1925. Serial No. 68,539.

The present invention relates to fasteners used for fastening together papers, and especially to fasteners of the pin type.

The primary object of my invention is to provide an improved fastener of the pin type which in addition to performing its function as a fastener for papers in an improved manner, performs also the function of an advertising medium, and which at the same time is capable of being manufactured at a low cost. In this connection, it will be appreciated that the matter of cost is of primary importance in a device of this character, and I consider the adaptability of my improved structure for manufacture at alow cost as being a very important feature of my invention. For a consideration of what I believe to be novel and my invention, attention is directed to the following description and the claims appended thereto.

In the drawing, Fig. 1 is a face View of a pin fastener embodying my invention; Fig. 2 is a side View thereof; Fig. 3 is a sectional view; and Figs. 4 and 5 are face and side views respectively of a modification.

Referring to the drawing, Figs. 1 to 3, the embodiment of my invention there illustrated comprises a pin portion 1 and a head portion 2, the two portions being formed integral with each other. The pin is integral with the edge of the head and extends across the back of it and to a point well beyond its confines to make it convenient in.

use.

New to reduce the cost of manufacture of a device of this character to a very low value, and also to render it small, compact and light in weight, it is necessary that lb be made from thin material, and to enable this to be accomplished, and still provide a pin which has strength sufficient to perform its intended function, I bend the ma terial which forms the pin longitudinally as is indicated at 3, the end of the pin being beveled as is indicated at 4 to-make it sharp. This serves to stiffen the pin and to give it enough strength so it will not bend when being pushed through the papers to be fastened together. The arrangement shown forms a longitudinally extending groove in the pin. I have found that by this arrangement the pin pierces the papers more readily and easily than with a fiat pin,

and is less likely to tear them when being inserted. Also, it holds the papers better and is less likely to come out. Since the fastener is made from thin material, the edges of the pin portion are fairly sharp and by providing a pin made from material bent longitudinally, the likelihood of a user cutting a finger on one of the edges when handling the pin is less than would be the case otherwise, for in holding the pin, the user does not grasp the two edges directly.

At the point where the pin is joined to the head, thereis an outwardly projecting portion 5 so that at this end the pin is spaced some distance from the rear surface of the head. It then extends across the head at an angle to the plane of the head so that the pin is closer to the surface of the head at the side opposite to that at which it is attached to the head. lVith this arrangement when the pin is passed through several thicknesses of paper to hold them together, it exerts a spring act-ion due to its being forced away from the head which serves to squeeze the papers between the pin and the head, thus increasing the grip of the fastener on the papers. This angular arrangement of the pin has the further advantage that when the fasteners are placed in a box orcontainer, the head of one fastener is prevented from being caught between the head and pin of another fastener, a thing which would tend to make the fasteners unhandy in use. On the outer surface of head 2 is means which forms a monogram as is indicated at 6, for advertising purposes' This may be in the form of any suitable indicia stamped, enameled or otherwise placed thereon. It is so placed on the head that the pin extends at an angle of about 45 degrees to it so that when the pin is used to fasten together papers, being inserted at an angle as is the usual custom when pinning together papers, the monogram will be straight with the papers. This serves to give the best appearance to the monogram.

The large head, in addition to providing a surface upon which a monogram is placed, serves also to provide a surface of large area against which the papers are held by the pin. This provides considerable friction between the head and the papers which assists in keeping the pin from coming out. Also,

with the large head, the head cannot be pulled through or is not likely to wear through one or more of the papers, a thing which oecurs some times with ordinary pins. Furthermore, the largehead is of use in inserting the pin through papers as it provides a convenient part to hold in the fingers and upon which to push.

In addition to lowering the cost of manu facture, the making of the fastener from very thin material ha s the advantage that the edges of the pin are thin so that a sharp cutting edge is provided without special sharpening.

I prefer to have the pin extend across the hack of the head for by this means I obtain the benefit of a relatively long pin without increasing unduly the overall length of the fastener, as well as the other advantages pointed out above. However, I may arrange the pin so that it doeznot extend across the. back of the head but extends directly from one edge of the head outward. This arrangement is shown in Figs. at and 5 wherein 7 indicates the head and 8 the pin of the fastener, the pin being grooved as before as is indicated at 9.

In fastening together papers, the fastener is used in the same manner as is an ordinary pin, thepapers being pinned together by the pin portion of the fastener. When used,

the monogram appears on the face of the papers and so in addition to its function of holding the papers together, it serves as an advertising medium.

My improved fastener can be formed from very thin material and as a single stamping. As a result it can be manufactured very cheaply so that it can be sold at a price making it practical for use as a paper fastener.

What I claim as new and desire to secure by Letters Patent of the United States, is

1. A paper fastener comprising a head and a grooved pin foi'medintegral with the eege of the head and extendingacross the back of the head at an angle to the plane of the head and to a point well beyond-the conlines of the head, said fastener being formed from thin sheet material, and the material of the Pill being bent longitudinally toforin the groored pm, said head being adapted to have advertising indicia on its outer isurface.

A paper fastener comprising a flat head having advertising indicia on its outer sur face, and a pin formed integral withthe head and extending across the back of the head at an angle of about a5 degrees to the line of the indieia, the end of the pin extending well beyond the confines of the head.

in witness whereof, I have hereunto set my hand this 9th day of November, 1925. DUDLEY M. DIGGS.
